Description
The present invention relates to fizzy granules and fizzy tablets
containing pesticide.
BRIEF DESCRIPTION OF FIGURE
FIG. 1 shows a VAT used in test example 2
As the fizzy granules and fizzy tablets containing pesticide, there have
hitherto been known those described in Japanese Examined Patent
Publication Nos. 24360/1970, 27930/1972 and 20128/75.
These formulations had problems such as poor stability during storage.
That is, both carbonates and solid acids are present in the conventional
formulations, which are observed to generate carbon dioxide gas due to the
absorption of moisture in air during their storage in a container such as
a kraft bag, a polyethylene bag or a polyethylene bottle and thus cause
the problem of decreasing the weight of the product. These formulations
also have problems such as the deterioration of disintegrability in water,
dispersibility in water or diffusion ability in water upon storage for a
long period. Furthermore, when these preparations are stored in a
polyethylene-laminated aluminium bag having no gas permeability, the bag
is often expanded by the generated carbon dioxide gas.
There is the danger of breaking the bag at the violent reaction.
In consideration of the states, the present inventors have found a fizzy
granules and fizzy tablets comprising a pesticidal active ingredient, a
surface active agent, a carbonate, a solid acid and at least one selected
from boron oxide and metaboric acid and having an excellent storage
stability.
The present invention relates to a pesticidal formulation (referred to
hereinafter as the composition of the present invention) comprising a) a
pesticidal active ingredient, b) a surface active agent, c) a carbonate,
d) a solid acid and e) at least one selected from boron oxide (B.sub.2
O.sub.3) and metaboric acid, wherein at least one of the carbonate and the
solid acid is water-soluble, the total content of the carbonate and the
solid acid is in a proportion of 5-90% to the total weight, the weight
ratio of the carbonate to the solid acid is in the range of 1:10-10:1, and
the weight of the boron oxide and/or metaboric acid is in a proportion of
0.5-40%, preferably 1-15% to the total weight.
In the composition of the present invention, the pesticidal active
ingredient used is not limited specifically and includes the following
compounds, active isomers thereof or mixtures thereof.

In the composition according to the present invention, the addition of a
calcined product precipitated hydrated silicon dioxide produced by the wet
process or a silica produced by the dry process is preferred when the
active ingredient has a melting point of lower than 70.degree. C. That is,
additives such as water-soluble carriers, water-soluble polymers, mineral
carriers, solvents, lubricants or disintegrating agents are incorporated
in addition to the essential active ingredient, the surface active agent,
the carbonate, the solid acid and boron oxide and/or metaboric acid
according to necessity.
In the composition according to the present invention, the pesticidal
active ingredients may be used alone or in admixture of the two or more of
them with an optional mixing ratio. The contents of these active
ingredients vary depending on the kinds of the ingredients and are in the
range of 0.01-80% by weight, preferably 0.1-50% by weight in proportion to
the total weight of the composition of the present invention. In addition,
when these active ingredients are liquids or are employed in the form of a
solution in a solvent, the calcined product of precipitated hydrated
silicon dioxide produced by the wet process or the silica produced by the
dry process exhibit only insufficient effect as an oil absorbing agent at
a content of the liquid ingredient containing the solvent exceeding 60% by
weight to the total weight of the composition of the present invention.
Thus, the content of the liquid ingredient should be usually in the range
of 0.01-60% by weight, preferably 0.1-40% by weight.
The amount added to the calcined product of precipitated hydrated silicon
dioxide produced by the wet process or the silica produced by the dry
process is usually in the range of 50-200% by weight, preferably 60-100%
by weight to the total liquid ingredient which is a liquid active
ingredient or a solution in a solvent. For example, a synthetic hydrated
silicon dioxide (silica produced by the wet process) such as Tokusil G-UN,
Tokusil P, Tokusil U, Tokusil N (manufactured by Tokuyama Soda Co., Ltd.),
Carplex #80 (manufactured by Shionogi & Co., Ltd.) Carplex #67, Carplex
#1120, Carplex #100, Carplex #22S, Carplex FPS-1, Carplex FPS-2, Carplex
FPS-3, Carplex FPS-4, Nipsil (manufactured by Nippon Silica) or Ultrasil
(manufactured by Degussa) calcined at a temperature of
700.degree.-900.degree. C., preferably 800.degree.-900.degree. C. is used
as a calcined product of a silica produced by the wet process.
Commercially available products such as Carplex CS-5, Carplex CS-7 or
Finisil P-8 (manufactured by Tokuyama Soda Co., Ltd.) may be used as such.
On the other hand, as a silica produced by the dry process, there is
employed a light silicic anhydride such as AEROSIL 200 or AEROSIL 300
(manufactured by Degussa).
Furthermore, when the active ingredient has a melting point in the range of
0.degree.-70.degree. C., a solvent is added, if necessary, in order to
decrease the viscosity of the ingredient at its production and to prevent
the crystallization of the active ingredient upon storage at a low
temperature. As the solvent, there is usually used a non-volatile or
sparingly volatile organic solvent. The solvents used for regulating
viscosity and preventing crystallization of the active ingredients include
those which are homogeneously mixed with the active ingredients, for
example, aromatic hydrocarbons such as phenylxylethane ketones, negetable
oils, mineral oils, liquid paraffin, polyethylene glycol having an average
molecular weight in the range of about 200-600 which is liquid at room
temperature, polypropylene glycol, and glycol ether such as polypropylene
glycol methyl ether and acetate thereof, particularly phenylxylylethane,
glycol ethers and acetates of glycol ethers are preferred.
The added amount of the solvent is usually in the range of 10-1000% by
weight, preferably 30-200% by weight to the amount of the active
ingredient. The aforementioned solvent may be added, if necessary, for
lowering the viscosity at production, even if the active ingredient has a
melting point of 0.degree. C. or less.
As the surface active agents used in the present invention, there can be
mentioned anionic surface active agents such as alkyl aryl sulfonates,
alkyl naphthalene sulfonates, lignin sulfonates, dialkyl sulfosuccinates,
polyoxyethylene alkyl aryl ether sulfates, alkali metal salts of
copolymers having carboxyl groups and fatty acid salts and noinoic surface
active agents such as polyoxyethylene alkyl ethers, polyoxyethylene alkyl
phenyl ethers, polyoxyethylene styryl phenyl ethers, polyoxyethylene alkyl
esters, sorbitan alkyl esters and polyoxyethylene sorbitan alkyl esters
which are able to emulsify and disperse the active ingredient and the
calcined silica according to the wet process. Also, there may be used
cathionic surface active agents, or amphoteric surface active agents
according to necessity. These surface active agents are used alone or in
admixture of the two or more. The used amount of the surface active agent
is usually in a proportion of 0.1-70% by weight, preferably 1-40% by
weight, more preferably 3-20% by weight, to the total weight of the
composition of the present invention.
As the carbonate used in the composition of the present invention, there
are mentioned for example sodium carbonate, potassium carbonate, lithium
carbonate, ammonium carbonate, calcium carbonate, sodium bicarbonate,
potassium bicarbonate, lithium bicarbonate, ammonium bicarbonate,
potassium sesquicarbonate and ammonium sesquicarbonate. Sodium bicarbonate
or sodium carbonate is particularly preferred. The aforementioned
carbonates are used alone or as a mixture of the two or more at any
ratios.
As the solid acid used in the composition of the present invention, there
are mentioned for example citric acid, succinic acid, maleic acid, fumaric
acid, tartaric acid, oxalic acid, malonic acid, malic acid, adipic acid,
boric acid, sodium dihydrogen phosphate, potassium dihydrogen phosphate,
benzoic acid, sulfamic acid, salicylic acid, ascobic acid, glutamic acid,
asparatic acid, sorbic acid, nicotinic acid and phenylacetic acid.
Particularly, maleic acid, fumaric acid, citric acid, succinic acid, boric
acid, malic acid and tartaric acid are preferred. These acids are used
alone or as a mixture of the two or more at any ratios.
The total amount of the carbonate and the solid acid used is usually in a
proportion of 5-90% by weight, preferably 10-70% by weight, more
preferably 20-60% by weight to the total weight of the composition of the
present invention. The weight ratio of the carbonate to the solid acid is
usually in a range of 1:10-10:1, preferably 1:5-5:1, more preferably
1:3-3:1.
Boron oxide and metaboric acid used in the present invention can be used
alone or as a mixture of the two or more at any ratios.
Also, as the water-soluble carrier, the water-soluble polymer, the mineral
carrier, the lubricant and the disintegrating agent, there are mentioned
the following materials.
First of all, as the water-soluble carrier, there are mentioned urea,
lactose, ammonium sulfate, sugar, sodium chloride and sodium sulfate.
As the water-soluble polymer, there are mentioned hydroxypropyl cellulose,
methyl cellulose, methylethyl cellulose, polyvinyl alcohol, polyvinyl
pyrrolidone, hydroxypropylmethyl cellulose, sodium carbonxymethyl
cellulose, and polyethylene glycols having an average molecular weight of
6000-20000.
As the mineral carrier, there are mentioned kaolin clay, diatomite, acid
clay, talc and attapulgite clay.
Moreover, the lubricant includes magnesium stearate, or titanium oxide, and
the disintegrating agent includes microcrystalline cellulose.
When these water-soluble carrier, water-soluble polymer, mineral carrier,
lubricant and disintegrating agent are added, the amount added is usually
in a proportion of 0.1-50% by weight, preferably 0.5-20% by weight to the
total weight of the composition of the present invention.
Furthermore, it is also possible to add appropriately a stabilizer, an
effect stimulating agent, a colorant, a perfume, or a builder to the
composition of the present invention.
The composition according to the present invention, of which active
ingredient has a melting point of 70.degree. C. or more, can be produced
by pulverizing the active ingredient alone or a mixture of it with either
one or all of the surface active agent, the carbonate and the solid acid
with a dry pulverizer such as air mill, pinmill or hammer mill, and then
mixing them with the residual ingredients. When the active ingredient is
liquid or in the form of liquid by the addition of a solvent, the
composition may be produced in the same manner as above after the active
ingredient is absorbed into the calcined product of silica produced by the
wet process or the silica produced by the dry process.
The powderous composition of the present invention obtained thus can be
used as such, but it is desirable to us it in the form of granule or
tablet in consideration of its handling, safety or environmental effect.
In this connection, the granule means the granulated product of the
powderous composition of the present invention, of which shape varies
depending on granulation methods and is in a wide range of cylindricals,
sphericals or irregulars. Also, the tablet means a product of the
powderous or glanular composition of the present invention compressed into
a certain shape, which is in a variety from the ones having sharp edges or
rounded edges to the one of a lens having shallow curvature, such as a
pillow shape, an almond shape, a finger shape, triangle, square, pentagon
or a capsule shape.
The granule can be prepared by forming the powderous composition of the
present invention into a granulated product in the form of sheet, pillow
or slugs with a dry granulating machine such a roll compactor or a
briquetting machine or with a slug machine, respectively, and breaking the
granulated product or slugs with a screening apparatus. In this
connection, the granule is preferably subjected to sphering treatment with
a Marumerizer (Produced by Fuji Paudal Co., Ltd.) or the like in order to
prevent dusting on its transport or use. If the compacting machine is
used, the powderous composition is placed between rotary rolls and is
pressed at 30 kg/cm.sup.2 or more, preferably 50 kg/cm.sup.2 or more. This
method uses no water, and carbon dioxide gas is not generated during the
production process, so that when the granule is applied to a paddy field,
a pond or a river or diluted with water, effervescence is observed more
sufficiently.
The aforementioned granule has usually a particle diameter in the range of
about 10000-100 .mu.m, preferably about 4000-297 .mu.m.
The tablet may be prepared by tableting a certain amount of the powderous
composition of the present invention by hand. In an industrial scale,
tablets having a certain weight can be continuously prepared by tableting
the aforementioned powder or granule in a tableting machine or a
briquetting machine.
The tablet may be in the sizes suitable for its applications and usually
has a diameter in the range of about 7-60 mm, a thickness in the range of
about 1-40 mm and a weight in the range of about 0.1-100 g, preferably
about 1-50 g.
The composition of the present invention is directly applied to an
irrigated paddy field, a river, a pond, a field, a lawn, an orchard, a
non-cultivated field, or it is used as an appropriate dilution with water.
When the composition of the present invention is applied to an irrigated
paddy field, the applied amount thereof varies depending on the kinds or
amounts of the active ingredients and is usually in the range of about
50-2000 g, preferably about 500-1000 g per 10 are.
When the composition of the present invention is applied directly, no
special devices are generally required. For instance, an operator gets
into a paddy field and applies the composition of the present invention
uniformly or to one or more places of the paddy field, or he applies the
composition to the sides of the footpaths of the paddy field or to the
water inlet of the paddy field or distributes the composition from the
footpaths without getting into the paddy field, so that the active
ingredient can be distributed and diffused to all of the paddy field.
Also, the composition can be applied by a motorized granular application
at a footpath or dispersed into air with a helicopter, an airplane or a
radiocontrolled airplane.
When the composition of the present invention is applied to an irrigated
paddy field, a pond or a river, it moves by the generation of carbon
dioxide gas and the active ingredient is rapidly and uniformly diffused
into water. Thus the pesticidal ingredient against pests, harmful
microorganisms or weeds exhibits sufficient effects on pests or crops,
respectively, and is diffused uniformly, so that the composition of the
present invention is also a composition excellent in the point of reducing
the phytotoxicity of pesticides. Also, when the composition of the present
invention is applied to a paddy field, the applied amount thereof can be
reduced extensively, so that the composition is also useful in the points
of the production, transport, storage and labor-saving dispersion of the
product. Furthermore, when the composition of the present invention is
used as a dilution with water, it generates carbon dioxide gas in water
and thus is disintegrated, dispersed or emulsified easily, so that it can
be handled conveniently.
The present invention is further explained in detail with reference to
preparation examples, comparative examples and test examples, but it is
not limited thereto. In addition, parts in the preparation examples and
the comparative examples indicate parts by weight.
